Nest T3016US - Programmable Thermostat

PURCHASE DATE: 27NOV15 PURCHASE PRICE: $211.44 COMED UTILITY COMPANY REBATE: $100.00 After purchasing a new home and watching our utility bills rise for a while I vowed to change all of that in 2015. I began to purchase LED light bulbs as a start, new energy efficient appliances, and then September 2015 the Nest 3rd Generation was released which caught my attention. I asked my father in-law who had the Nest 2nd Generation for information and he had nothing negative to say about it so I was sold. After comparing it to other competitors I was hooked on this one due to the ease of installation, good reviews, and $100 electric company rebate (ask your local energy company). Do not be intimidated to install this on your own it's not hard. The instructions it comes with and YouTube to be on the safe side did it for me. Before installing please make sure to shut your homes power panel breaker prior to uninstalling the old thermostat and installing the Nest (be safe). Take a picture of the way the wires were installed on your old thermostat prior to uninstalling. In doing so this will ensure that your connections are connected correctly. Test your wires one more time prior to uninstalling to make sure no power is running (avoid being shocked or damaging anything). I did not use/install the base-plate (pictures shown) because I wanted a modern, sleek, and clean look. The body and display (40% increase) of the 3rd generation is slightly larger then that of the 2nd generation. If you have children you can lock it so that a child touching it can not change or disrupt your temperature or any of your settings. The stainless steel dial is very smooth and allows you to navigate through the settings with ease. It takes the Nest a couple of days to remember what temperatures you like when you are home and at what times you are home. After a couple of days Nest will ask you if you want it to automatically go into Away Mode when it senses you are not home (you decide opt in or opt out - I opted in). I recommend opting in to Away Mode for better energy savings. You can control when you are home and when you are away during those few days or if you opt out of Away Mode then you control it all. Smartphone application is free and easy to use. The new Far-Sight feature is awesome and can catch me at approximately 10 feet away even in the dark. When Nest detects any motion it will illuminate with what the current temperature is. This is how it can tell if you are home or not and can automatically place itself in Away Mode for energy savings. Being able to control everything from the application on my smartphone itself is so awesome (fan, cooling/heating mode, humidity level, away/home mode, set a schedule, history, etc.). Nest will remind you when you should change your air filters on your furnace because it can base it upon how many times it turns on and off. Significant drop in energy consumption can be seen on my gas bill after month 1. Due to this my father purchased the item as well and has no complaints thus far. UPDATE: 15FEB17 Still own the item with no problems. If you are doing research and thinking of purchasing it - just do it! It is paying for itself in savings thus far. Highly recommended! (PICTURES ATTACHED) THANK YOU!

I have a lot of observations to make about this product. I'll start with what I was faced with first. I live in a 2 story house, purchased last July. I live in South Carolina, where it's very humid and we rarely use our heating systems. The heater with air handler is located in the attic. The house was built in 2003. No one has ever replaced the contractor-installed Bryant brand heater. I've had these heaters before, and they are annoying. Whenever I replaced them in the past with a Trane furnace, my bill was cut in half and none of the ridiculous traits of the Bryant happened anymore. Those being the following: Cold spots in different places all over the house. A long ignite time, which means it's blowing cold air on you from the vents before it finally ignites. Too long to ignite. Uneven heating everywhere. Too hot upstairs, too cold downstairs. When the temps got below 35, it was unbearable downstairs unless I cranked it up to 70, which is a high temp for me on the thermostat in the winter. My AC condenser was replaced recently, so in the summer the air conditioner handled everything very well. It is a 4 ton unit and unrelated brand to the Bryant. (not a very good plan, but at least the AC works well). The AC has none of the issues that the furnace has. It works great. There's a problem, though. Because past owners pieced together a different AC system, the two systems are not as efficient as they could be. They also just can't put in a furnace and make it all work. Not the kind of efficiency furnace I've bought before. I just needed a furnace, but not an AC unit. So, I set out to talk to all these Trane installers. I love the two stage AC units from Trane because they only go into the higher mode when they really have to. The answer I got? "You can't change out only one unit. It has to be both." (something I knew from previous houses, anyway). Installer: "That's going to cost you $13,000.00" Me: "Gulp. I know that they really need to both be married up, in order for them to work well." Installer: "No other way, with this pieced together system you have right now." The problem with this? I didn't have the cash. Lowes would only loan me $6,000 at no interest. I always went for no interest loans in the past. Wells Fargo would only give me 5,700.00 but I could not combine both of these financing options. No one would loan me (or anyone else) that much money. I could've gone with a personal line of credit at my bank, but it was 10 - 12 %. Banks are a lot tighter with home improvement loans these days, since GE sold its finance division to a company called MySynchrony. GE gave me 15,000.00 no interest for the first year once. Not anymore. So, I set out to get 4 more quotes. Same answer from all of them. So, I was stuck with running downstairs to turn the heat down at night because I felt like I was going to suffocate upstairs, then running downstairs in the morning to turn it up to get it warmer down there. Then I remembered the Nest. It's expensive, yes. But .....it is better to at least try to spend $248.00 instead of 13 grand. (All the quotes I got were pretty much the same.) At the very least, I could incorporate it into a new system in the future. Install: Easiest install of any thermostat I've ever performed. I've always done my own installs because I liked Honeywell for many years, but there are no screws or difficult, cramped holes to put the wires into. You don't have to read a book to figure out which wires to use and guess what kind of system you have. It already knew, once I installed it. It's connected to the Internet through your WIFI. If I'm upstairs with the heat on and it gets too hot up there, I just pick up my iPhone, go to the app and adjust it. If I want to go downstairs in the morning and know I have it set to 65 down there, I just heat it up a bit on my iPhone before I get out of bed. It learns. I'm not quite sure what it will learn from me, because I'm retired and usually keep things about the same. But, the programming was extremely easy, both on the unit and on the iPhone app. Change it anytime I want. I was at the doctor yesterday. Realized that just my dogs were at home and I had started the AC this past weekend. (You can switch between heat and air any time you want on the iPhone or iPad app...awesome. ) So, I just turned up the AC to a warmer temp because my dogs aren't too crazy about it being really cold. Before I got home, I set it back to 70 for AC, where I like it. I was bed-ridden after some spinal injections this past weekend. I was praising this thing for making my life comfortable while I recuperated upstairs. Before, it would've been absolute agony to go downstairs all the time because South Carolina is in Spring already. You never know what the day will be like. I just changed it when I needed to on my iPhone. The WIFI was easy to connect, once I realized that you turn the unit itself with a rotating dial either left or right, then press on the choice you want. No annoying methods to type in your password like it is on a Bluray player to login to an app like Netflix. Those are a pain. The screen is motion-sensing on the unit, so you just have to walk by or wave your hand to see its settings. It seems to also get my systems to the correct temperature WAY faster than my Honeywell thermostat did. Seconds vs minutes. Now: I've saved $13 Grand. For now. It's made my furnace manageable in a two story house. I can save up the cash for a new system. It has a mode called Airwave that is supposed to save you on AC costs. I'll know in July and August if that works well. I believe it's going to save me a lot of money and allow me the time to save up for the new system that I really want. I will have my installers just leave the Nest there. It's an incredible product. I've not found one bug with it yet. It's only been about 5 days, but it is already telling me it is learning. Love this product. So glad I bought it. It's the best piece of technology I've bought so far, besides the iPad Pro. Thank you Nest. You saved me a lot of money for now. A few months later: This product is already saving me a lot of money. It's already saved me $40.00 this month on electric. One thing I wanted to mention was someone was complaining about the way it displays the temperature. I think that it is just a matter of getting used to it because there is a rare occasion that the large number in the middle and the smaller number are not the same. What I've noticed is it gets my system up to the correct temperature way faster, and so I'm really not so concerned with the smaller number anymore. I also saw that someone was complaining about the Away function if you don't walk in front of it often and waking up to a cold house. I'm retired, so I don't really need a regular Away function. I go out at really different times, so I went into the settings on the App and turned that off. Problem solved. I love that my air conditioner doesn't run as much as it used to, and I noticed I don't have as much cold air coming out of the vents when the heater is working. I also get an email of my usage each month from Nest. (see image) The leafs mean you've set your temp to an energy-saving setting and will also show up on the dial. And It's still saved me 13 grand. Win win for me.

I ended up buying this thermostat directly from Nest.com because they had a promotional discount on the 4th of July. I was very happy with this purchase as there are rebates for Southern California Edison and SoCal Gas for buying this thermostat with continuous rebates throughout the year. I really do love this thermostat, not only is it incredibly functional, it's very beautiful on the wall replacing an ugly old school Honeywell system that was easily 16 years old. Things I love: * Installation was very simple and Nest makes it easy by going online first and doing a compatibility check and shows you a wiring diagram you should print off. I'm no electrician and could easily do this install in about 15 min once I had the diagram and the tools in front of me. * The integrated feel - it connects to your wi-fi, you have an app for iPhone (and I believe Android), you can control it online in a traditional browser. Besides doing it's job it's keeping track of energy usage and helping to show you where you can be saving. Plays well with other internet of things, like Amazon Alexa and IFTT * The trim plate - the ugly old Honeywell system i had left a large square mark on the wall, the trim plate that came with Nest easily covered that up and it looks beautiful. * Senses when you walk by or approach and lights up to show you the current temperature, and outside temperature (gleans from wifi weather) * Intuitive interface, you press in the lower part of the thermostat to bring up a menu and you rotate the dial and press again to make choices, very simple and easy-to-use. * Partnership with energy companies - besides a rebate with gas and electric companies, they have a partnership with a solar company in my area I'm going to check out. Strong partnerships like that can lead to highly efficient systems and reducing cost (hopefully). What I don't like: * As a geeky nerd, I'm a little disappointed that I have to use the interface to connect to my wifi. If you have a very secure wifi password that is long, this will be a test of patience. In other devices, I'm used to it broadcasting it's own connection that you can securely connect to and set the password on with another device, like your iphone. I wish this kind of option were available, or other kind of pairing ease-of-use. * The auto-schedule that tries to learn your pattern in the first few days can be a little grumpy. For example, I had my power off on a hot day when installing. Once I got it installed it was quite warm in my house. I turned it on and immediately set to 65. I later adjusted that, but over the next few days it set itself to 65 until it figured out that wasn't a normal thing. Overall, I like the auto-schedule, it's just in the first few days you'll be scratching your head. * Don't do like me and set to 65 if you'd be happy at 71, for example. Just set your ideal, not a drastic temperature. * When you first turn it on, it may not be immediately apparent how to achieve what you want. I put it on hot/cold (by accident) and was trying to figure out how to just cool the house when I was staring at the heating screen. Stick with it and it will get easier in a day. The iPhone app is a lot easier to deal with, but once you get used to the interface, you won't give it a second thought after 2-3 days. * Cost.. it's expensive. Nest had a 4th of July sale for $50 off which made it attractive along with the rebates is like $175 off. But, you do get a lot more for your money. Final thoughts: If you plan to do more home automation, or already have a home automation system, be sure to know if this will work with it. For example, at the time of writing this I'm considering a SmartThings Hub system by Samsung which apparently Nest does not have a working partnership with Samsung on, so Samsung doesn't have a supported connection to Nest thermostat (although there are developer work-arounds that work). It does work well with Wink Hub system. This isn't an endorsement for either SmartThings or Wink Hub but it's a good idea to know this information if you have the desire to integrate and update more items in your home like lighting, locks, sensors, etc that require a hub of some sort.

If I can install this... Anyone can! So, when I first bought thing, I was nervous about getting it installed. I had an electrician lined up (even thought they wanted an arm and a leg to install it)... Well, I am not a patient person, so I decided to take my Nest out of the box and see if I could figure this whole installation thing out... OMG, EASY PEASY!!!!! I turned off my system at the breaker box, took off the face of the old thermostat, took a picture of the wires and continued to disassemble. OK, I was 1/3 of the way there - yay me! I start to unpack the Nest from the box and look at all the parts and felt confident I could do this. I have the instructions out and was following them step by step. The only time I had to go to The Google was when it came to hooking up the wires... I have no problem with the Red, Green or White... Yellow confused me, but The Google came through and explained that if I didn't have a multi-zoned system I needed to use Y1. All hooked up, face of my pretty, shiny, perfect Nest was on! Woohoo! Back to the breaker box, turn on my HVAC system and low and behold my perfect Nest was practically smiling at me! I followed the prompts on the screen - tentatively at first because I was worried she was fragile - and step by step I became more comfortable using the device. Even better than a pretty face - SHE WORKS! I set my temperature and BINGO, fan and heat kicked on! I was so excited, I called my neighbors over to come and see my handy work and called the guy I was seeing at the time to tell him that he was in fact incorrect - I didn't need a man to install and set this up for me (we're not talking anymore, btw)... Any questions I had, I went to the Nest twitter page, asked my questions via DM, and the replies have been prompt and polite. My questions have been answered satisfactorily and I was able to keep truckin'. Now, she knows when I am home, and syncs with my life - My Nest has given me one less thing to worry about... I can crawl into bed and set the temperature where I want it and be comfortable. Full disclosure, I had a digital programmable thermostat before. What I like most about my Nest is being able to have more control over my energy bill: I'm at work and I decide to meet the girls for a drink. The heat isn't running waiting for me to come home. Instead, when I get in the car (I work about 15 minutes from home), I open the app, set the temperature and when I get home the house feels cozy! If I stay up late and don't want the temperature to drop before I hit the sack, I can set it when I crawl into bed... Sleeping in late, when I get up, I open the app, set the temperature and in 10 minutes, I can hop out of bed and not freeze! She's learning how I live and makes adjustments based on my "schedule" and she knows based on my iPhone's location services if I have left the house for a quick minute, am running errands in the hood or am just going out to gossip with neighbors or if I am out of town... She doesn't turn on the heat or AC just because the house sitter came in to feed the manimals. I love seeing the hours (actual amount of time) that I am using the heat (or AC). When my HVAC guys came the other day for a plumbing issue (completely unrelated to my Nest) they took one look at her and couldn't stop telling me how "sleek" she looks and asking questions... Apparently the guy they had at their company to install smart devices had a very hard time installing them and explaining to residents how to use them... I was shocked! I couldn't speak for other devices - but told them that if I could install the Nest a trained professional should have no problem! They offered me a job - LOL. I can't say enough good things about my Nest. She's perfect. If she were a dude, I'd seriously try to find him on Bumble... ;)

I bought a Nest thermostat, partly to learn about it from a professional standpoint, and partly because I was excited to try it out. People are raving about them. Bottom line: after several days of trying it out and setting it up, I got so angry at it that I took it off the wall, put back the ancient one that it was replacing, boxed it up, and I'm returning it. I *never* return *anything*, so this is notable. The thing that's wrong with Nest is that it isn't very good at its basic function: being a thermostat. There are two things that it should do: Determine the temperature in the room, and the desired temperature, and try to make the room be the desired temperature. Turn the furnace on and off. On the first point, yes, it kind of does that, but it doesn't show you the current temperature in the room -- only the desired temperature. It knows the current temperature in the room, right? And every other thermostat on the market shows you both temperatures, right? So why is it that there is literally no way to see the current temperature in the room? The only answer I can think of is: "design". We didn't want to mess up the beautiful display by showing you two numbers because that would look bad. Right. Good decision. On the second point, turning the furnace on/off, the brand-new 3rd Generation Nest with a fresh software update ... fails miserably. The furnace runs for a while, then I think when the room temperature is just about the desired temperature, it starts to cycle the furnace on/off every 3- 4seconds, for quite a number of minutes. As a programmer, I'm pretty sure this is because the temperature sensor is not quite accurate enough, so when it's on the line between 68 and 69, let's say, it flips back and forth (maybe the temperature is 68.5643 and it rounds off to 68 then to 69 then back to 68 as the temperature fluctuates 0.001 degrees. This is so basic to the functionality of a thermostat that they probably have internal brown-bag lunches on this topic at Honeywell, when you join the thermostat engineering group. Except they don't seem to have thermostat engineers at Nest, just "user experience designers." Fail. Okay, it sucks at being a thermostat, but isn't it awesome as an Internet of Things poster child? Sort of. The app is nice, and it does show remote status pretty well, and remote control (except for that part about "what temperature is the room, anyway?). But it's focused on saving energy, which is great, but it is not very focused on making me warm on a cold day, which is the other reason for having a thermostat. Auto-Away Nest has a feature they call Auto-Away, which uses the built-in motion sensor to decide whether or not you're home (a pretty good idea) and turns the furnace down when you're not around. This would be great, except for WHEN YOU ARE HOME, and just NOT IN FRONT OF THE THERMOSTAT. Motion detector delays are pretty standard, right? Like your motion detector light fixture on your front porch. There's a switch on there to decide how long a delay you want. Nest's Auto-Away feature has exactly one control: ON or OFF. That's it. You can't set the delay for how often you walk by the thermostat. It seems to have a really short one, like 10 minutes, after which it decides you aren't home and TURNS DOWN THE HEAT. That is so completely not helpful, on a cold day. When you find yourself getting out of your chair many times during a day and walking into the room with the thermostat in it and waving your arms, to try to make the heat go back on, you start to realize that the product is badly designed and implemented. Which brings me to the last feature, the ability to control the furnace from someplace else. This is totally great, and works well. AND YOU NEED IT, becuase you have to turn Auto-Away off, because it sucks and that's your only choice (ON or OFF). But if Auto-Away is off, then you have to turn it off remotely if you are Away, and forgot to turn the heat down. Fail. Epic fail, all in all, because it has all the ingredients of being awesome, but absolutely sucks at doing its basic job.

I am actually quite impressed by this thermostat. Our vacation home in the mountain does not have an air conditioner -- just an old furnace. I knew nothing about HVAC at the time, but the thermostat helped me understand that what I had was just that: a furnace wired with just two cables. That also meant that the existing cabling would not allow for an air conditioning unit to be installed without additional wiring. There are workarounds available, but the point is: my Honeywell smart thermostat would not work with just two wires. It needed a C (Blue Common) wire to power itself. The Nest? "No problem", my brother told me. So, I bought a Nest and sure enough, it works with just 2 wires. The app guides you on the installation: 1. Scan the QR code found on the thermostat with the app 2. Turn off the power to the thermostat, heater, and air conditioning unit 3. Locate the existing wires, take a photo so you could go back to it 4. Label the wires with included, sticking labels 5. The app then tells you exactly what each wire is for and how to connect them to the Nest. When I installed the Nest at my home later (that has so many more wires), I learned that I have a stage 1 and 2 heater and an air conditioning unit. RC is for power, C for Common wire. 6. Once wired, turn back on the power 7. Nest guides you through some questions, asking you what kind of heater you got. Then it allows you to test the heater, AC, fan 8. You can then continue with the app to configure additional options, including scheduling TWO NUMBERS? WHICH IS WHICH? I saw two numbers on the Nest. Which was the current temperature? Which was the temp we wanted the thermostat to heat up to? The outer number is the current, ambient temperature. The center one is the desired temp to reach. READ TEMP DOESN'T MATCH ACTUAL? What if the Nest's current temp doesn't match the actual temperature in your home? This happened to me. Nest showed 68 degrees. Home was actually 72. Turns out, that is normal. Nest says that the thermostat was still adjusting to the home and learning. Give it 24 hours to see if the read temp matches actual. It did for me. As long as your Nest was not near a source that could affect its temp reading (ie. near a water heater), the thermostat should learn and adjust its sensor to match actual reading. SCHEDULING I found scheduling to be quite awkward. Go to each day and click Add. Then adjust the temp by swiping up or down, time by going left or right. This can be frustrating at times: where I meant to go up/down, it registered left/right. You also can't easily see what temp you were setting because your darn finger is in the way! Try to set different temps for different days... and boy. It gets frustrating. I liked something less flashy like my older Honeywell: choose the days, type in or push arrows to the desired temp and time. SO MUCH QUICKER to configure. Function over looks. Google... The thermostat learns from your habits and schedules and adjusts itself accordingly. This should, in theory, help you save some money by only turning on the heater/AC as needed. This learning mode can also be turned off entirely. Sharing the thermostat's control unfortunately requires a Google Home app configuration to which you invite your family member to. You cannot share control via the Nest app itself. Shame on Google. For my vacation home, I do like that you can lock what temp range you want a guest to be able to adjust to. I set mine up to between 50-72F. No need for someone to go hotter or colder than that. I also love that there's a safety function: even when the thermostat is turned off, if it detects ambient temp to reach a pre-determined level (I set mine to 47F), it'll automatically heat the house to that minimum. This is important for our vacation home that's up in the mountains to help minimize the danger of our water pipes from freezing during rigid winters. Suffice to say, I liked the controls this thermostat offered, I got my own home one too. Check out your utility company to see if any rebates are available. They might have a program to help offset some of this Nest's cost.

So the gentleman who posted the top review that says "Will not display the current temperature -- by design!" is incorrect at worst and misleading at best. I just installed one of these and it will display the current temperature, it's just not in huge numbers. When you walk up to the unit it will know you're there, and display what you have the heat/cooling set to and then will switch to the mode that lets you see what the temperature is. The temperature will be noted with a hash mark/notch and a number. I've included a picture here to show what I'm talking about and the stock amazon photo shows the same thing. If you look at my picture you will see where my unit is set to heat at 66 degrees and cool at 74. In between those numbers is 72, which is the current temperature. I also included a picture where I turned the dial to go to cool to 71 degrees and the display still shows the current temp at 72. In Amazon's stock picture the unit is set to heat up to 68 degrees and the current temperature is 65 degrees, as indicated on the upper left hand side of the picture. If you tap the unit it will pull up the main display screen which has the temp as well. Maybe the gentleman didn't understand the differences here or he had an older firmware than what it uses now. Regardless, I don't feel it's fair to knock this unit for not displaying the temperature even though it does. It's not in giant numbers, but it's pretty easy to tell what the current temperature is if you take a moment and look. The current temp is on dispaly immediately if you're looking at the unit. Now to the actual review. This unit was very easy to install, the big pain was getting my old thermostat off of the wall. Nest has a interactive website for the installation of this unit (nest.com/works) that makes it easy to figure out if your current wiring will support one of these newer thermostats. You log onto the Nest site and chose the wires that you have coming out of your thermostat and from there the Nest site will tell you if you can use the Nest thermostat with your current setup. I would suggest looking that up before you purchase this unit. Or if you too like to live dangerously, do what I did and pull up the site on your iPad after you've bought the unit. With that out of the way, the unit comes with a back plate that you will connect your wires to. Before you do this, turn off the power to your HVAC system. I like to live dangerously, but not THAT dangerously. Connect the wires to the back plate, attach the unit to the wall and flip your breaker. The unit will light up and guide you through a pretty easy set up. NOTE: You do have to have wifi to get this unit to work properly. If you do not have wifi do not bother purchasing this thermostat. The thing I like the most about this thermostat is I can set a threshold for heating and cooling. Every house I've lived in has always had thermostats that seemed like they were from the 1970s so I don't know if this feature is normal on new thermostats, however this is a game changer for me. Where I live the temperatures can vary by 40 degrees each day and having a thermostat that will let me run the ac in the evening and then turn on the heat at 2 am when the temp drops is worth every penny. I literally have set the thermostat and left it alone since installing it. Some other cool features of this thermostat are that it keeps track of how much heating and cooling you do each day if you're into metrics, and it has a feature called "Sunblock". When you install the thermostat it asks you where you're installing it (such as a bedroom, hallway, kitchen, etc) and if the unit is in direct sunlight. If it is the unit will use Sunblock, which uses the light sensors in the thermostat to determine when it's under direct sunlight. This is used to learn the sun’s patterns in relation to your house the temperature sensors to detect the heat spikes that occur in direct sunlight. It then links to your wifi and knows when the sun rises and sets in your area. Sunblock will use that information to set the correct temperature whenever it’s in direct sunlight and not waste energy. Again, this is a game changer. My previous house had a thermostat that was near direct sunlight and close to a computer so it would run the AC when it wasn't needed, and jack up our electrical bills. There's an app as well that lets you control the temperature if you're lazy and don't want to get up, and to set the temp in the house while you're away. Overall I think this is a really cool product, and if the features I've mentioned are something you'd be interested in then I think it's worth the money. It's especially worth it if your power company has a rebate for purchasing one of these units. That can bring the cost down $50-$100 dollars.

Alright... I'll preface this review with the usual "I don't post reviews often," but this 3rd gen Nest Learning Thermostat is so great at what it does that I simply have to tell the world and recommend it any skeptics. I think part of the reason why I'm giving it five stars, and why I was so surprised to see that this thermostat actually works, is because I was severely skeptical of it. I have a traditional radiator heating system (no central air) in an early 2000s home. While the home still felt brand new, with modern interior decor, we just had a dated heating system. Don't know why. Anyway, I didn't think that I would benefit that much from Nest—I'm missing out on the cooling and fan features—but those drawbacks still don't outweigh the million other things that this thermostat gets right. The thermostat that this Nest replaced was old as hell. It had a digital display, but it never worked properly for us for some reason. It gave us incorrect temperatures. For example, with our old thermostat we would set it to 80 degrees but the heat failed to creep past what felt like 72 degrees. It was always a bit chilly in the house, which made us arbitrarily force our old thermometer into a higher set temperature. Setting up the Nest was a little complicated at first. Granted I only had two wires to connect (W1 red and Rh black), it was my own fault for not reading the instructions properly. Taking off the old thermostat revealed a metal box underneath and I accidentally attempted to drill the Nest + trim plate into the metal box. After a few days, the Nest was wobbling around, so I removed it and decided to put on the metal plate, then the trim box, then the Nest, and now it sits perfectly against the wall with no movement. Perfect. (Also I don't understand some of the complaints that the white trim plate that is included is "ugly"? It looks fine... I mean, it's a trim plate and it does what it's supposed to. Honestly the other trim plates I've seen sold on Amazon are way aesthetically uglier.) At the time of writing this, the Nest is still trying to learn my behavior, but so far it's created a pattern that is actually accurate. The one gripe I do have is that the auto-away feature takes forever to kick in and sometimes I feel like I'm wasting energy by heating a home nobody is occupying. But the status of the auto-away is still "learning," so I will remain hopeful and allow it to do its thing. One of my favorite things about this thermostat is that it knows when my brother will be home from school at exactly 4:30 PM everyday, so since we have a radiant heating system, Nest automatically starts heating the house at 3:30 in order to get the temperature to our desired/comfortable temperature by the time he gets home. In addition, after a few days of tuning it to my preferred temperature right before I go to bed, it now automatically switches to that temperature a little bit before I climb into bed so that it's comfortable when I decide to snooze. Last note: the design of this thing is gorgeous. I'm a graphic designer at an ad agency and I was stricken by how gorgeous the display and easy to use the user interface of Nest is. Simple, intuitive, and the mobile companion app is amazingly straightforward and easy to use. I was fearful of what would happen to Nest after Google acquired it, so I waited a while to purchase one for myself. But I couldn't resist with the 3rd gen. If you're still a skeptic or mixed about getting Nest, I highly recommend that you do. This is my first Internet-of-Things purchase and I'm in love.

La instalación no es tan sencilla como el que tiene solo calefacción, de hecho me tuvieron que ayudar amigos . Este modelo es el internacional, que ademas de la calefaccion tiene aa. En españa todavia esta de manera masiva, asi que me decidi por este. Al final encontramos unas guías por internet de instalacion. Quitando esto, en si con el producto estoy encantada. Es estético y sobretodo me permite ahorrar un dispositivo y creedme controlar aa y calefaccion no tiene precio. Yo al menos, lo recomiendo

I did some renovations on the main floor, after all was done, I decided to go with this thermostat and replace my old one due to its compact design. I do not regret changing to Nest, excellent thermostat, nice compact design, look amazing on my dining room. Temperature management works great. I just need to mention, right now it is summer, if something work different on the winter I'll update this review. I do recommend this product 100%, It is not cheap but it worth the money. I do recommend, if possible, run five wires from furnace to this thermostat, it does need "C" wire otherwise you might need to jump wires at the furnace's board.

Attention cette version ne contient pas le module HEAT LINK qui s’installe sur la chaudière. N’est pas précisé dans l’annonce... Je l’ai renvoyé

Not every thing is easy linking to Alexa with analogue as the functions are not as flexible as you might think. At this time tech support does not work well. I have a combi boiler underfloor heating and radiators and there are issues that are not easily resolved.

In local market they will give you the same product at AED 999. In Amazon, you get it at much less. This is a very good quality product. Must buy.
